#### 36.4.3 Base64 and Binary Data Transmission

Some transmission channels can not accept binary data. It is customary to encode binary data in Base64 for transmission and to decode the data upon reception.

: s = base64_encode (x) ¶

  Encode a double matrix or array x into the base64 format string s.

  See also: base64_decode, matlab.net.base64decode, matlab.net.base64encode.

: x = base64_decode (s) ¶
: x = base64_decode (s, dims) ¶

  Decode the double matrix or array x from the base64 encoded string s.

  The optional input parameter dims should be a vector containing the dimensions of the decoded array.

: b64_str = matlab.net.base64encode (in) ¶

  Convert in to a base64 encoded string b64_str.

  The input in can be a string or numeric vector. The output b64_str will be encoded according to RFC 4648.

  See also: matlab.net.base64decode, base64_decode, base64_encode, unicode2native.

: out_vec = matlab.net.base64decode (b64_str) ¶

  Convert base64 encoded b64_str to uint8 vector out_vec.

  The input b64_str must be a string vector. The output out_vec will be a uint8 vector that is decoded according to RFC 4648.
